Description

technical field [0001] The invention belongs to the technical field of missile defense, and in particular relates to a method and system for acquiring elements of long-range interception and launch based on a single-sided shooting table. Background technique [0002] There are usually two methods for the calculation of missile launch parameters: one is the shot table method, that is, the corresponding relationship between the three-dimensional space position in the interception area and the launch parameters is calculated in advance, and the shot table interpolation is used to read the launch data according to the predicted interception point. parameters; the other is the Newton iteration method, by establishing the functional relationship between the launch parameters and the predicted intercept point, using Newton iteration to calculate the deviation of the launch parameters and correcting the initial values, and gradually obtain accurate parameters . The advantage of the...
